It appears that Amazon is introducing a new service specifically targeted at Relational Databases helpful hints. You can choose from MySQL, Oracle, and Microsoft Sql Server.
Amazon Relational Database Service (Amazon RDS) is a web service that makes it easy to set up, operate, and scale a relational database in the cloud. It provides cost-efficient and resizable capacity while managing time-consuming database administration tasks, freeing you up to focus on your applications and business.
If you have been around computer systems long enough everyone knows how import disk performance is, espeacially with database systems. There’s the standard htparm -tT and dd test the everyone does, but it really does give you the whole picture. What you really want is to test read, write, re-read, re-write, read backwards, read strided, fread, fwrite, random read, pread ,mmap, aio_read, and aio_write. For that I would recommend using Iozone. It gives you a better idea of what’s going on.
If you are like me and want to install git-core core from source instead of one to the many binary packages out or you just have a distro that does have a binary for it. Here is what you will need to get it installed.
Once all you have verified or install on the required packages. You can download the source from Git Homepage.
shell$ wget http://git-core.googlecode.com/files/git-1.x.x.tar.gz
shell$ tar -zxf git-1.x.x.tar.gz
shell$ cd git-1.x.x
shell$ ./configure –prefix=[install_path]
shell$ make all
shell$ sudo make install
A little old school and not the hard.

The other day I and a few of my colleges were talking about a easy way to deploy and undeploy war files from the command line like you could through the Tomcat Web Application Manager portal and being on a python kick, I started writing it in python. After an hour or two I realized that I had made this way more complex then I need to. I had been reading theApache Tomcat 6.0 Manager App HOW-TO and I was using curl to test all the commands from localhost.
shell> curl –anyauth -u admin:password http://localhost:8080/manager/start?path=/myapp
So now after slapping myself in forehead and saying “duh!”. I decided I could write this as shell script and have it knock out in 20 minutes.
So here what I came up with tomcat-cli.sh.

And point you web browser at http://localhost:9001 and see what happens.
